Climate Change Climate change refers to the variation in the Earth's global climate or in regional climates over time. It describes changes in the variability or average state of the atmosphere - or average weather - over time scales ranging from decades to millions of years. These changes may come from processes internal to the earth, be driven by external forces (e.g. variations in sunlight intensity) or, most recently, be caused by human activities. In recent usage, especially in the context of environmental policy, the term "climate change" often refers to the ongoing changes in modern climate, including the rise in average surface temperature known as global warming. In some cases, the term is also used with a presumption of human causation, as in the United Nations Framework Convention on Climate Change (UNFCCC). The UNFCCC uses "climate variability" for nonhuman caused variations. photo source

Featured Organizations & Resources Campus Climate Challenge is a project of more than 30 leading youth organizations throughout the U.S. and Canada. The Challenge leverages the power of young people to organize on college campuses and high schools across Canada and the U.S. to win 100% Clean Energy policies at their schools. The Challenge is growing a generation-wide movement to stop global warming. Stop Climate Chaos seeks to build a massive coalition, that will create an irresistible public mandate for political action to stop human-induced climate change. South African Climate Action Network SACAN is a network of like-minded Non-Governmental Organisations (NGOs), Community Based Organisations (CBOs) and individuals working on climate change issues in South Africa. Climate Solutions seeks to stop global warming at the earliest point possible by helping the Pacific Northwest and British Columbia become world leaders in practical and profitable solutions. International Council for Local Environmental Initiatives ICLEI is an international association of local governments and national and regional local government organizations that have made a commitment to sustainable development. ICLEI's mission is to improve the global environment through local action. On the issue of global warming, we provide resources, tools, and technical assistance to help local governments measure and reduce greenhouse gas emissions in their communities. Climate Change Education is a hub website dedicated to global warming science education. CarbonCounter is a collaborative project to address the threat millions face each year from the effects of global climate change. photo source Climate Change Discussion photo source Join a discussion on Climate Change and exchange ideas about Climate Change or discuss how you would like this page to look.
